Understanding Osteoporosis
What happens to the structure of bones as osteoporosis develops?
What is becoming less dense and more fragile?
Why is calcium important for the skeleton?
It is a major mineral component of bones and helps maintain their structure.
What important role does vitamin D play in the body’s use of calcium?
It helps the body absorb calcium from the digestive tract.
What is a weight-bearing activity that puts stress on bones through gravity?
What is walking, jogging, or dancing?
What is one reason osteoporosis becomes more common with increasing age?
Bone loss can gradually exceed bone formation over time.
What are the two main processes involved in maintaining bone tissue?
What is bone formation and bone breakdown?
What is the difference between calcium naturally present in food and calcium added through fortification?
Naturally occurring calcium is already in the food; fortified calcium is added during processing.
What can happen to calcium absorption if the body does not have enough vitamin D?
Calcium absorption can become less efficient.
How can muscle-strengthening activities support bone health?
Muscle contractions place forces on bones that can help maintain bone strength.
Why are older women more prone to osteoporosis?
Menopause can cause the loss of estrogen, a hormone in women that helps maintain bone mass.
Why can a person have osteoporosis without experiencing pain?
Bone loss often occurs without noticeable symptoms.
Why might someone who avoids dairy need to pay attention to other sources of calcium?
Dairy products are common sources of calcium, so other sources can help meet nutritional needs.
Name two foods that may provide vitamin D.
What is fatty fish and vitamin D-fortified milk?
Why is physical activity important for more than just building muscle?
Certain types of activity can also support bones, balance, and mobility.
What is the difference between a risk factor and a symptom of osteoporosis?
A risk factor increases the likelihood of a condition; a symptom is something a person experiences because of it.
What is the difference between bone density and bone strength?
Bone density measures how much mineral is in bone, while bone strength describes its ability to resist breaking.
Besides calcium, name one nutrient that helps support the maintenance of bone tissue.
What is protein, phosphorus, or magnesium?
How are calcium and vitamin D different in their roles in bone health?
Calcium provides a mineral building block for bones, while vitamin D helps the body absorb calcium.
How can smoking affect bone health?
Smoking is associated with reduced bone health and an increased risk of fractures.
What does a DXA scan measure when evaluating bone health?
Bone mineral density.
Why can a fracture from a minor fall be a warning sign of osteoporosis?
Fragile bones may break from impacts that would not normally cause a fracture.
Why is getting calcium from food one way to support bone health?
Foods such as dairy products, calcium-set tofu, and fortified plant milks can provide calcium the body uses to maintain bones.
Why is vitamin D important beyond simply being another nutrient in the diet?
It supports calcium absorption and normal bone mineralization.
Why are balance and coordination relevant to osteoporosis, even though they do not directly increase bone density?
They can help reduce the likelihood of falls, which may cause fractures.
Why can measuring bone mineral density be useful even when a person has no symptoms?
It can identify low bone density before symptoms or a fracture occur.
